Pennsylvania 19 Claims.

MyV` invention relates to small cars such as used in industrial plants for transporting products from one part of the plant to another andis more especially designed for carrying boxes used in charging open hearth furnaces.

One of the objects of the invention is to produce a car of this type of rolled shapes andcast metal which are welded together to form a unitary structurethereby eliminating the use of riv- 10 ets and at the same time form a car which will be light of weight but of maximum strength for a vminimum amount of metal used.

Another object of my invention relates to the manner of forming and reinforcing the end structure of the car.

Another object of the invention is to provide means for bracing the central portion of the car. .A further object of the invention relates to construction of the pedestals for the iournal boxes.

ai) These and other objects will be apparent from the specification and appended claims.

Referring now to the three sheets of drawings forming a part of this specification:

Figure 1 is a top plan view of the car; Fig. 2 is a side elevation;

Fig.`3 is an end elevation; Fig. 4 is a vertical transverse section taken on Y the line 4-4 of Fig. 1;

v`Fig. 5 is a longitudinal section through one end of the car taken on the line 5 5 of Fig. 2; Fig. 6 is a central vertical longitudinal section through one end of the car taken on the line 6 6 of Fig. 1;

Fig. 7 is a vertical section through one of the side sills, journal box and pedestal therefor taken on the line 'I-'I of Fig. 2 with the wheel shown in elevation; v

Fig. 8 is 'a top plan of the end portion of a car showing a modied form of a draft rigging I may use; and

Fig. 9is a vertical longitudinal section taken on the line 9-9 of Fig. 8.

Referring now to the various characters of reference on the drawings, and first to Figs. 1 to 7, inclusive: The side sills are indicated as I and are formed of rolled H or I-b'eam section disposed with their webs vertically and the anges extending laterally therefrom along the top and bottom edges. The ends of the side sills are connected together by meansof top and bottom plates 2 and 3 which are of greater widthat the central portions and have converging end portions notched as at 4 and welded to the top and bottom ilanges asv at 5. A draft casting 6 of inverted Ufshape is 5| disposed centrally between the top and bottom PATENT oFF-ICE assignor to a corporation of plates at each end of the car having a top wall portion y'I and spaced downwardly extending vertical legs 8 having a portion diverging toward the end of the car and formed with outwardly extending anges 9 and I Il at the upper and lower 5 edges which are weldedl to thetop and bottom plates as at II. The draft castings each have abutments I2 and I3 formed therein for engaging the front and rear follower plates I4 and I5. Springs I6 are interposed between the follower v10 plates and a bolt Il passes through the springs and the follower'vplates having a nut I8 threaded on its inner endrand a head I9 on its outer end for attaching the drawbar 2|] thereto. The inner edges of the top and bottom plates between the l5 draft casting 6 and the side sills are connected Ltogether by means of vertical plates 2|, whilethe outer edges of said top and bottom plates are connected together on each side of the draft casting by means of vertical plates 22 and 23 which 20 are welded together as at 24 an'd to the end of a vertical longitudinally extending rib plate 25 which connects and is welded to the top and bottom plates 2 and 3 and the inner vertical plate 2 I.

The ends of the outer flanges of the side sills I 25 and the top and bottom plates 2 and 3 are connected together by means of a filler plate 26.- As each of the draft castings 6 are open at the bottom side, the bottom plate 3 which extends the full width of the car is adapted to support the 30 draft rigging and is provided with a central opening 21 for inserting or removing the follower plates I4 and I5 and the springs I6.

The central portion of the car is provided with an X-brace formed of angles disposed with their 35 legs extending downwardly, comprisingV a single angle 28 which is continuous and has its opposite ends welded to the side sills at each side of the Ycar and a pair of angles 29 each having'an outer end welded to one of the side sills and the inner 40 ends welded centrally to the angle 28 as at 30.

Pedestals 3I are welded to the lower surfaces of the side sills, each formed of spaced vertical side plates 32 forming the guide ways for the journal boxes 33. The top ends of the side plates 45 32 are welded to the lower surface of the side sills and are connected by means of a spring seat plate 3'4.'Each of the side plates 32 has a brace plate 35 having its upper end welded to the under surface of the side sills and its lower end flanged 50 as at 36 and welded to the lower end of the vertical side plates 32. The lower flanged end 36 is perforated to receive a bolt 31 for attaching a pedestal tie bar 38 thereto.

The wheels for the car are indicated at 33 55 mounted on axles 40 which have their ends journaled in boxes 33 of well known standard construction having recessed side guides 4I for engaging the vertical side plates 32, an upwardly extending boss 42 upon which a spring 43 is mounted and is also provided with roller bearings 44, cylindrical sleeves 45 and 46, thrust plate 41 and retaining cap 48.

The charging boxes 49 are adapted to be seated directly on the tops of the side sills l which are provided with a plurality of spacing members 50 formed ofA angles having their legs extending isiiclzlwnwardly and welded to the tops of the side Referring now to the modification shown in Figs. 8 and 9. In this construction the coupler i is attached directly to the end Iof the car by means of bolts 52 while the draft casting and end plate structure is the same as shown and described for Figs. 1 to 7, inclusive, and the same referencenumerals will apply thereto.

Although I have shown and 'described my inventiun in considerable detail, I do not wish to be limited to the exact and specific details shown and described, but may use such substitutions, modifications or equivalents thereof, as are ernbraced within the scope of my invention or as pointed out in the claims.
